Compare and contrast. The lives of Mantegna and Bellini were entwined through rivalry, friendship, creative confederacy and also as brothers-in-law. Their shared talents brought innovation to their world and inspiration to the Renaissance painters who followed them and paved the way for the development of modern art. A fabulous new show at the National Gallery in London celebrates this astonishing artistic relationship with a stunning collection of paintings many of which have never been seen in the UK before.
